IMPROVEMENT IN DUMPING-CARS.

Specification forming part of Letters Patent No. [82,901, dated October3, 1876; application filed May 9,1876.

To all whom it may concern Be it known that I, EUGENE DAVIS, of Clinton,in the county of De Witt and State of Illinois, have invented a new andImproved Gar-Unloading Apparatus, of which the following is aspecification:

The present invention has reference to certain improvements in thatclass of car-unloading apparatus in which a tilting or swingingtrack-section is used in connection with a main track for running a caron and off said tilting section; and the invention consists in thecombination, with a centrally-pivoted track-section, of an arc-shaped orsegmental rack-bar engaging with a spur-wheel on a driving-shaft. By thearrangement of the rack-bar below the axis of the tilting tracksectionthe same can be depressed at either end by simply turning the operatinggearing in opposite directions, thus dispensing with two sets of devicesfor tilting the track.

Figure 1 is a longitudinal sectional elevation of my improvedcar-unloading apparatus, taken on the line 00 00 of Fig. 2; and Fig. 2is a transverse section, taken on line y y, Fig. 1.

A is a short section of the railway-track suspended on the frame B,which is pivoted at 0, above the track, "on the permanentlyfixed postsD, so as to swing in a vertical plane coincident with the track; and thebottom of said frame B is geared by the toothed segment E with thepinion F on shaft G, which gears by the train of wheels H with acrank-shaft, I, by which the track A is tilted. J is a pawl and K apawl-lever for holding the track by interlocking with wheel L whenrequired. N represents slide-bolts, and 0 levers to fasten it up level;and P, cords or chains attacked to posts of frame B and hooking intoeyes Q in the side of the car, to hold it on track A, when it is tiltedup for dumping out the car. R represents chutes to receive the materialfrom the cars and chute it into the proper receptacle.

In practice, this dumping apparatus will be arranged on a littleincline, so that the cars will run on and off by gravity. In operatingit the cords P will be hooked on the car at the end which descends justbefore the car arrives at the stopping-place; and the slidebolt on thedumping end will be withdrawn as the car comes to rest, so that theinertia will assist in tilting the car.

The apparatus may be set 011 any suitable foundation, and it maybeemployed for dumping into other cars, boats, bins, or pits, as desired.An upright shaft and bevel-gears may be employed to connect shaft G withthe crankshaft. I propose, in practice, to have the swinging frame sosuspended that it may be readily hooked onto a scale for weighing theload.

I am aware that it is not new to pivot a section of a railroad-track soas to tilt in either direction for the purpose of dumping cars, buthitherto the section has swung from a pivot below the track, thusrequiring an elevation of grade or a deep pit. I obviate this entirelyby swinging from a point above the track, and am enabled to place mychutes fixedly and directly under the track; hence What I claim is Thecombination of the arc-shaped rack E, shaft G, spur-wheel F, andsuitable operating devices, with the centrally-pivoted track-section A,stationary track, and discharge-chutes R, all relatively arranged as andfor the purpose set forth.

EUGENE DAVIS.
